Modulo range and ratio do not match
Cause
For multi-turn absolute value encoders, the ratio between the encoder
and load must be selected so that the complete encoder range is an
integer multiple of the modulo range.
The following condition must be fulfilled:
P1021 * P0238:8 / P0237:8 * 360 / P0242 must be integer numbers.
Remedy
– Check and correctP1021, P0238:8, P0237:8
– Adapt the modulo range (P0242)

Minus hardware limit switch
Cause
A 1/0 edge was identified at the ”Minus hardware limit switch” input sig-
nal.
Remedy
Return the drive into the traversing range using jog button 1 or 2. Then
acknowledge the fault.
Acknowledgement RESET FAULT MEMORY

Plus hardware limit switch
Cause
A 1/0 edge was identified at the ”Plus hardware limit switch” input sig-
nal.
Remedy
Return the drive into the traversing range using jog button 1 or 2. Then
acknowledge the fault.
Acknowledgement RESET FAULT MEMORY

STOP III
142
Input I0.x not parameterized as equivalent zero mark
Cause
When entering an external signal as equivalent zero mark (P0174 = 2),
input I0.x must be assigned ”equivalent zero mark” function (Fct.
No.:79).
if a direct measuring system is used, input I0.B must be assigned the
”equivalent zero mark” function (Fct. No.: 79).
Remedy
– Motor measuring system: P0660 = 79
– Direct measuring system: P0672 = 79

Endless traversing and external block change in block
\%n
Cause
The block change enable CONTINUE_EXTERNAL for the END-
LESS_POS or ENDLESS_NEG command is only permitted with P0110
= 0 or 1.
Remedy
Block change enable or change P0110.
